A 13-year-old girl with asplenia syndrome who previously had undergone left subclavian-to-pulmonary artery shunt after removal of a cavopulmonary shunt with interposition of a short segment of the left superior vena cava was admitted for congestive heart failure. Angiography revealed aneurysmal dilatation of the left superior vena cava. Percutaneous coil embolization of the shunt was successfully performed and the venous aneurysm was diminished. Interposition of a venous component in systemic-to-pulmonary artery shunt should be avoided even after removing a cavopulmonary shunt.

Objective: The antitumor effects of anti-PD-1 antibody against mismatch repair deficiency (MMR-D)-associated cancers have been reported. MMR-D is found in approximately 20%–30% of endometrial carcinomas (ECs) and frequently occurs due to MLH1 promoter hypermethylation (MLH1-PHM). ECs with MLH1-PHM are classified according to the molecular screening of Lynch syndrome (LS), but few detailed reports are available. The purpose of this study was to clarify the clinical features of EC with MLH1-PHM. Methods: Immunohistochemistry of MMR proteins (MLH1, MSH2, MSH6, and PMS2) was performed on specimens from 527 ECs treated at our university hospital from 2003 to 2018. MLH1 methylation analysis was added to cases with MLH1/PMS2 loss. ECs were classified as follows: cases that retained MMR proteins as “MMR-proficient;” cases with MLH1/PMS2 loss and MLH1-PHM as “met-EC;” and cases with other MMR protein loss and MLH1/PMS2 loss without MLH1-PHM as “suspected-LS.” The clinical features, including long-term prognosis, of each group, were analyzed. Results: Accordingly, 419 (79.5%), 65 (12.3%), and 43 (8.2%) cases were categorized as “MMR-proficient,” “suspected-LS,” and “met-EC,” respectively. Significantly, “met-EC” had a lower proportion of grade 1 tumors (37.5%) and a higher proportion of stage III/IV tumors (37.2%) than the other groups. The overall and progression-free survival of “met-EC” were significantly worse than those of “suspected-LS” in all cases. Conclusion In ECs with MMR-D, “met-ECs” were a subgroup with a poorer prognosis than “suspected-LS.” “Met-ECs” would be the main target for anti-PD-1 antibody treatment, and its clinical susceptibility should be verified individually.

[Objective] The purpose of this cross-sectional questionnaire-based study is to investigate the challenges of adverse events during treatment by acupuncture and moxibustion to an athlete. [Methods] In total, 1,804 subjects, including athletes who participated in marathons and university athletes were enrolled in this study. The survey was conducted by distributing the questionnaire or via online questionnaire to the athletes who fit the criteria for the study. The questionnaires were collected after consent was received from the participants; online questionnaires were also collected. The questionnaire was examined for age, sex, and type of competition, purpose of the acupuncture treatment and the actual effects, and treated area, content of adverse event, number of times the subjects received acupuncture, and informed consent, and free description of adverse events.[Results] In total, 1,525 (84.5%) valid responses to the questionnaires were received. The survey analyzed 841 subjects (55.1%) who experienced acupuncture and moxibustion. The following responses about adverse events of acupuncture were obtained: "pain at time of needle insertion"; 17.0%, "subcutaneous-bleeding"; 10.1% and "pain and feeling of heaviness due to the needle": 10.0%, among others. For moxibustion, responses included "burns"; 5.9% and "malaise"; 5.8%, among others. In the free description, there were 17 descriptions of discomfort due to excessive stimulation and difficulty in movement during exercise. Of the questions regarding whether or not they received informed consent, 215 were received orally (25.6%), 34 were received in written form (4.0%), 99 were received both orally and in written form (11.8%).[Discussion and Conclusion] Acupuncture for athletes causes a certain rate of adverse events. It was suggested that guidelines for athletes to receive acupuncture safely and training and education for practitioners are important.
